BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a bracket device, and more particularly, to a bracket device adapted to a slide rail and a rack system.

2. Description of the Prior Art

As shown in FIG. 1, a carried object 100 is conventionally mounted to a rack 104 by a slide rail 102 or a slide rail assembly in a rack system, wherein the slide rail 102 is equipped with a bracket device 106, which is configured to mount the slide rail 102 to the rack 104.

Furthermore, the bracket device 106 includes a bracket 108 and a fastening member 110, wherein the fastening member 110 is pivoted to the bracket 108 by a shaft member 112, and the fastening member 110 is able to pivot relative to the bracket 108 to a locked position P. When the fastening member 110 is located at the locked position P, a first engaging feature 114 of the fastening member 110 is engaged with a second engaging feature 116 of the carried object 100, such that the carried object 100 is retained at a position.

However, the fastening member 110 is pivoted to the bracket 108 by the shaft member 112 being disposed through a pivotal hole 118 of the bracket 108. In practical application, a hole size of the pivotal hole 118 is greater than a diameter of the shaft member 112 for specific purpose, such that the fastening member 110 is movable along a direction D with respect to the bracket 108 via the shaft member 112.

In such a manner, when the second engaging feature 116 of the carried object 100 is engaged with the first engaging feature 114, the fastening member 110 will vibrate up and down or be tilted by an external force F accidentally applied thereon, as shown in FIG. 2, which results in that the second engaging feature 116 of the carried object 100 is unable to engage with the first engaging feature 114 of the fastening member 110. Alternatively, the aforesaid issue occurs due to tolerance between the shaft member 112 and the pivotal hole 118 of the bracket 108.

Thus, how to develop a reliable bracket device has become an issue.

DETAILED DESCRIPTION

As shown in FIG. 3, a carried object 20 is mounted to a rack 24 by a slide rail 22 (or a slide rail assembly). In the present invention, the carried object 20 can be an electronic apparatus or a chassis. Hereinafter, it is illustrative that the carried object 20 includes a first portion 20 a and a second portion 20 b, and a width of the first portion 20 a is greater than a width of the second portion 20 b.

Furthermore, each of the slide rail 22 is mounted to a first post 24 a of the rack 24 by a mounting member 28 of a bracket device 26 and mounted to a second post 24 b of the rack 24 by another bracket device 30.

As shown in FIG. 4 and FIG. 5, the bracket device 26 includes a bracket 32 and a fastening member 34. The fastening member 34 is pivoted to the bracket 32.

The bracket 32 is coupled with the aforesaid slide rail 22. For example, the bracket 32 is securely connected to the aforesaid slide rail 22 in a riveting manner or in a welding manner. In practical, the bracket 32 includes a side wall 36 and at least one mounting member 28. The at least one mounting member 28 is adjacent to the side wall 36. Preferably, the bracket 32 further includes an edge wall 40. The edge wall 40 is substantially perpendicularly connected to the side wall 36, and the at least one mounting member 28 is disposed on the edge wall 40.

In the present first embodiment, the bracket 32 includes a first structure 42, and the fastening member 34 includes a second structure 44. The first structure 42 includes two protruding portions 42 a, 42 b. The two protruding portions 42 a, 42 b laterally protrude from the side wall 36, and the second structure 44 is an extended wall of the fastening member 34. The second structure 44 is arranged between the two protruding portions 42 a, 42 b. Preferably, the side wall 36 of the bracket 32 has an opening H, and the two protruding portions 42 a, 42 b are disposed on an upper side and a lower side of the opening H, respectively. On the other hand, the second structure 44 is located corresponding to the opening H.

Preferably, the bracket 32 further includes at least one protruded lug 46. The at least one protruded lug 46 is disposed on the side wall 36, and the at least one protruded lug 46 has a guiding feature 48. The guiding feature 48 is oriented identically to a length direction of the side wall 36 (or the aforesaid slide rail 22). Hereinafter, it is illustrative of an example that the guiding feature 48 is an elongated hole oriented longitudinally. On the other hand, the fastening member 34 is pivoted to the bracket 32. In the present invention, the fastening member 34 is pivoted to the guiding feature 48 by a shaft member 50 being disposed through a portion of the guiding feature 48. For example, a size of the guiding feature 48 is slightly greater than a diameter of the shaft member 50, such that not only the fastening member 34 is able to pivot relative to the bracket 32 by the shaft member 50, but also the fastening member 34 is able to move relative to the side wall 36 of the bracket 32 along the guiding feature 48.

Furthermore, the fastening member 34 includes at least one connecting portion 52, a fastening portion 54 and an engaging feature 56. The at least one connecting portion 52 is disposed between the second structure 44 and the fastening portion 54, such that the shaft member 50 is disposed through the at least one connecting portion 52 and the at least one protruded lug 46. The engaging feature 56 is adjacent to the fastening portion 54. For example, the engaging feature 56 is a hook, and the engaging feature 56 is connected to the fastening portion 54 and disposed adjacent to a front end of the fastening portion 54. The engaging feature 56 is configured to be engaged with another engaging feature 58 of the carried object 20 (or called target object) mounted to the aforesaid slide rail 22. Preferably, the bracket device 26 further includes a resilient member 60. The resilient member 60 is configured to provide the fastening member 34 with a resilient force.

As shown in FIG. 5 and FIG. 6, the fastening member 34 is able to be moved from a locked position P1 (i.e., a position) to an unlocked position P2 (i.e., another position) along a pivoting direction R, or alternatively, from the unlocked position P2 to the locked position P1. Preferably, the fastening member 34 is forced to retain at the locked position P1 by the resilient force provided by the resilient member 60.

When the fastening member 34 is at the locked position P1, the fastening portion 54 of the fastening member 34 is adjacent to the at least one mounting member 28, as shown in FIG. 5. When the fastening member 34 is not at the locked position P1, e.g., when the fastening member 34 is at the unlocked position P2, the fastening portion 54 of the fastening member 34 is away from the at least one mounting member 28, as shown in FIG. 6.

As shown in FIG. 7, when the slide rail 22 is mounted to the first post 24 a of the rack 24 by the at least one mounting member 28 of the bracket 32 and the fastening member 34 is at the locked position P1, the fastening portion 54 of the fastening member 34 is used for locking the first post 24 a, and the engaging feature 56 of the fastening member 34 is used for being engaged with the other engaging feature 58 of the carried object 20 as the carried object 20 is illustrative of being at a retracted position L via the slide rail 22.

In practical, when the fastening member 34 is at the locked position P1, the second structure 44 is in cooperation with the first structure 42, so as to prevent the fastening member 34 from moving along an axis direction X of the shaft member 50. In other words, the second structure 44 and the first structure 42 are able to prevent the fastening member 34 from moving along a height direction relative to a longitudinal direction of the side wall 36 or the slide rail 22.

For example, when the fastening member 34 is at the locked position P1, an external force F1 or F2 is accidentally applied on the fastening member 34, it is able to prevent the fastening member 34 from moving upwards or downwards that the second structure 44 is abutted between the two protruding portions 42 a, 42 b. In other words, the two protruding portions 42 a, 42 b of the first structure 42 in cooperation with the second structure 44 are able to prevent the fastening member 34 from moving upwards, downwards or along a tilted direction relative to the side wall 36 of the bracket 32.

In summary, when the fastening member 34 is at the locked position P1, the aforesaid configuration ensures that the engaging feature 56 of the fastening member 34 is engaged with the other engaging feature 58 of the carried object 20. One of the advantages of the aforesaid configuration is to prevent the fastening member 34 from disengaging from the carried object 20.

As shown in FIG. 7, it should be noticed that a first width W1 is defined between the two protruding portions 42 a, 42 b of the first structure 42 of the bracket 32, a second width W2 of the second structure 44 of the fastening member 34 is defined along a height direction relative to a longitudinal direction of the bracket 32, and the second width W2 is substantially identical to the first width W1. As a result, the second structure 44 can be constrained between the two protruding portions 42 a, 42 b of the first structure 42, and the two protruding portions 42 a, 42 b of the first structure 42 are able to prevent the second structure 44 from moving upwards, downwards or along a tilted direction relative to the bracket 32.

As shown in FIG. 8 and FIG. 9, the major difference between the bracket device 200 in the second embodiment and that in the first embodiment is the configuration of the first structure and the second structure.

The first structure 202 and the second structure 204 of the bracket device 200 are a combination of a protruding portion and a hole. In practical, the bracket 206 includes a first structure 202. For example, the first structure 202 is illustrative of a protruding portion adjacent to the edge wall 208. On the other hand, the fastening member 210 includes a second structure 204, and the second structure 204 is illustrative of a hole. The hole is for accommodating the protruding portion, such that the protruding portion is constrained by inner walls of the hole. In such a manner, the combination of the first structure 202 (i.e., the protruding portion) and the second structure 204 (i.e., the hole) is able to prevent the fastening member 210 from moving upwards, downwards or along a tilted direction relative to the bracket 206. In an alternative embodiment, the first structure 202 can be a hole, and the second structure 204 can be a protruding portion.

In summary, when the fastening member 210 is at a locked position P1, the aforesaid configuration ensures that an engaging feature 212 of the fastening member 210 is engaged with the other engaging feature 58 of the carried object 20.

As shown in FIG. 9, it should be noticed that a first width W1 is defined by the first structure 202 of the bracket 206 along a height direction relative to a longitudinal direction of the bracket 206, a second width W2 is defined by the second structure 204 of the fastening member 210 along the height direction, and the second width W2 is substantially identical to the first width W1. As a result, the second structure 204 (i.e., the hole) can accommodate the first structure 202 (i.e., the protruding portion), and the second structure 204 (i.e., the hole) is able to prevent the first structure 202 (i.e., the protruding portion) from moving upwards, downwards or along a tilted direction relative to the bracket 206.

As shown in FIG. 10, the major difference between the bracket device 300 in the third embodiment and that in the second embodiment is the configuration of the first structure and the second structure.

The first structure 302 and the second structure 304 of the bracket device 300 are a combination of a protruding portion and a hole. In practical, the bracket 306 includes a first structure 302. The first structure 302 is illustrative of a hole disposed on the side wall 308 of the bracket 306. On the other hand, the fastening member 310 includes the second structure 304. The second structure 304 is illustrative of a protruding portion configured to be inserted in the hole, such that the protruding portion is constrained by inner walls of the hole. In such a manner, the combination of the first structure 302 (i.e., the hole) and the second structure 304 (i.e., the protruding portion) is able to prevent the fastening member 310 from moving upwards, downwards or along a tilted direction relative to the bracket 306. In an alternative embodiment, the first structure 302 can be a protruding portion, and the second structure 304 can be a hole.

In summary, when the fastening member 310 is at a locked position P1, the aforesaid configuration ensures that an engaging feature 312 of the fastening member 310 is engaged with the other engaging feature 58 of the carried object 20.

As shown in FIG. 10, it should be noticed that an amount of the first structure 302 (i.e., the hole) of the bracket 306 is two, and a first width W1 is defined between the two holes (i.e., the first structures 302). An amount of the second structure 304 (i.e., the protruding portion) is two, and a second width W2 is defined between the two protruding portions (i.e., the second structures 304). The second width W2 is substantially identical to the first width W1. As a result, the second structures 304 (i.e., the protruding portions) can respectively engage with the first structures 302 (i.e., the holes), and the first structures 302 (i.e., the holes) are able to prevent the second structures 304 (i.e., the protruding portions) from moving upwards, downwards or along a tilted direction relative to the bracket 306.

As shown in the second embodiment and the third embodiment, the first structure and the second structure can be a combination of a protruding portion and a recessed portion, and related descriptions thereof are omitted herein for simplicity.

In summary, the bracket device of the present invention has an advantage that the second structure and the first structure are configured to cooperatively prevent the fastening member from moving along the axis direction of the shaft member.
